Definitions

  • the invention relates to an apparatus and method for sealing tubes of a blown fiber cable as it enters a sleeve.
  • Sockets for fiber optic cables have two fundamentally different sealing systems, namely elastomeric cable seals in the lower housing part of the sleeve or shrink sleeves.
  • the invention is based on the technical problem of providing a device and a method for sealing tubes of a blown-fiber cable as it enters a sleeve.
  • the device for sealing tubes of a blown fiber cable when entering a sleeve comprises a sealing element Distribution element, a bundle element and at least one cover, wherein the sealing element has a number of tubes corresponding number of seals, wherein the cable side before the sealing element, the distribution element is arranged and sleeve side behind the sealing element, the bundle element is arranged.
  • This makes it possible to individually seal each tube, including the core, so that no moisture can penetrate along the tube into the sleeve.
  • the cover is at least above the sealing element and extends to the sleeve.
  • sealing element may also have more seals than tubes, in which case the unused seals must be closed, for example by means of a membrane.
  • the sealing element is preferably made of an elastomer. Further preferably, distribution element, sealing element and bundle element are connected to each other, for example, locked, glued or screwed.
  • the seals are arranged concentrically on the sealing element, more preferably at least two rings of seals exist.
  • the tubes can be sufficiently far apart, which simplifies handling in the implementation of the tube through the sealing element.
  • the seals on the sleeve side frustoconical protrusions can also be formed as a hollow cylinder.
  • the cover elements are designed as two elements with cap and tubular projection, wherein the caps enclose the sealing element.
  • the two caps can do this for example, locked together, bolted, glued or otherwise connected moisture-proof.
  • the tubular extension sleeve side serves for insertion into the sleeve, wherein the tubular extension is sealed by means of an elastomeric seal upon entry into the sleeve, wherein the cable-side tubular extension for connection by means of shrink sleeve with the cable sheath or a deferred instead of the flex hose is used , When using a flex hose, a further shrink sleeve is then preferably used to connect the cable sheath and flex hose.
  • the outer tubes are shortened compared to the inner tubes, so that first the inner tubes are passed through the sealing element and then the outer tubes, which simplifies handling. At a later time, the tubes can then be cut within the sleeve again to approximately the same length.
